Building in Berkeley
Renovation and millwork for Berkeley houses and their architects.
Greenport is a design-build general contractor and millwork shop in San Rafael, founded in 2012 by brothers Eli and Jacob Froneberger, both raised in Marin. We hold California General Building license #1073941, and we mill our own casework at 47 Louise St, a short drive from Berkeley.
Permitting
The City of Berkeley Planning and Development Department handles planning and permits, with design review, landmark review for designated properties, and hillside standards in the fire zones.
Housing stock
Brown-shingle and Craftsman houses in the hills and North Berkeley, bungalows in the flats, and a significant stock of architect-designed houses.
What decides the schedule
Design intent. Berkeley clients often come with an architect and a house worth respecting, so coordination and detail drawings carry the project.
